Giles pump for an N/A motor
« on: January 18, 2008, 07:24:32 pm »
What kind of power increase would I see with a Giles pump on a normally aspirated 1.6 motor?  Is the change dramatic?  Dyno numbers?  Thanks.

Giles did a pump for his N/A delivery rabbit a couple years ago. No other mods whatsoever. It gained 22hp at the wheels! That's the same as a 1.7L gasser rabbit, with more torque! I've always thought a Giles pumped, ported 1.9 head on a 1.6L with good exhaust would be a fun little ride. Stab on a TD Giles pump and reference the LDA to nitrous nozzle pressure for a kick in the backside.
He's sorted out several more mods to his pumps since that one. Most likely, it'd be better still.

I think this is amazing, was that with or without the exhaust up-grade?

Can it really be a full 22WHP? People are paying a fortune to get gains like that in a gasser...

I suppose the price differences between a Td pump and normal N/A one would be quite different also...Nice gain gilles.....!damn

This sounds good.  I've been thinking of just going the Giles pump route, until the motor gets a little weaker (it only has 110,000 miles on it).  Then going the full TD route.  Could I put a TD IP pump on an N/A in hopes of putting a TD in the car later in the future?

you could put a TD pump on, just make sure to have the boost line blocked off so no dirt/crap gets in there.

Best bet, as always is to call Giles directly.
905-940-2266

or check his full contact details post here:

a modded pump on an N/A engine is definitely not cause for an EGT or headgastket panic. The car ran flawlessly for two years before being sold, and continues to run flawlessly to this day. (I bet he wishes he kept it, now!)

yeah i also kind of wonder about what kind of power an na diesel could make... just take the intake off and run open ports for the intake... that will give you better high end power, then flip the exhaust manifold and run a 3 inch pipe out of the hood off the toilet bowl, plenty of flow with those 2 mods.  a good clutch and some sticky tires and i bet you could run an 18 flat in the quarter mile.  :roll: hahaha.  but for real i do wonder what kind of power they could make na

Actually you could probably do better with a tuned runner intake than with open ports. The reason is that at the tuned rpm, the pulses help the engine breath better than it could otherwise.

Jim, would the tuned intake be like a 4-2-1 exhaust in reverse?  I've never heard of such a thing.

Baselyne-  the idea here is for engines with no turbo at all.  playing with the intake and exhaust for increased flow is an old skool way of making power by a better naturally aspirated (n/a) flow of air and exhaust through the engine.  Since there is no turbo, you can play with the length and configuration of the pipes.  none of this applies to a turbocharged car.
I still don't understand how Giles can get that much more power than stock, even out of an N/A.  I would think Bosch would have grabbed him and taken him over to Germany by now.  :)  better get that performance diesel rebuild soon :D
